Well, yeah, there are still problems. But I don't see the problem you
see. In fact, the test cases I had work fine now. And the time
needed is much better (only between 2000% and 8000% slower :-).
The problems you might have experienced could be mine. I had to fix
several bugs in the tst-regex program. I've checked in a fixed
version now. This version passes with your patches applied. Only the
one test commented out with DOES_NOT_WORK doesn't work. It also fails
for the single-byte case which is worrisome.
If you don't see any problems with your patch I'd like to check it in.
Please provide a ChangeLog entries. In addition I'd like to ask you
to look at the one failing test.
Thanks,
